Construction + Civil Engineering

At a time when there have been numerous product recalls issued for concrete screw anchors due to concerns over their effectiveness, an innovative fastening solution continues to deliver peace of mind and is celebrating more than three decades of proven performance.

Launched in 1994, HECO MULTI-MONTI^®-plus screw anchors have been a dependable choice for the European construction industry for over 30 years. The tried and tested range is manufactured in the Black Forest by German screw specialist, HECO Schrauben, and is available in the UK from distribution partner, Aptus Fastener Systems.

Stewart Taylor, managing director at Aptus, comments: “There has been a spate of product recalls recently for concrete screw anchors. The issues with some of these anchors have been deemed so severe that they have been withdrawn due to fears they may fail, potentially resulting in structural damage or even injuries.

“In contrast, MULTI-MONTI^®-plus screw anchors have just passed a major milestone and are continuing to shape an enduring legacy. They owe this longstanding success to an intelligent design that has been continually refined over more than three decades. This design ensures unwavering reliability as well as a number of other impressive benefits.”

Specifically, HECO MULTI-MONTI^®-plus screw anchors offer a cost-effective alternative to chemical and expanding anchors, delivering comparable performance with greater versatility. They are also easy to use, being more forgiving of less than perfect installation conditions and techniques. For example, MULTI-MONTI®-plus screw anchors can be installed in all temperatures. Users can also achieve optimum results without meticulously cleaning drill swarf from the installation hole or applying an exact torque level.

In addition, MULTI-MONTI^®-plus screw anchors can be loaded with either static or quasi-static loads immediately, unlike chemical anchors which require time to cure.

Further benefits include a special thread geometry that ensures easier driving with less torque, increasing user productivity and output. This same geometry also reduces stress on the fixing and surrounding substrate, enabling applications closer to the edge.

The name MULTI-MONTI^®-plus is derived from “multi-functional mounting,” and as the name suggests, these anchors offer exceptional versatility. They can be used to fasten into various materials including concrete, natural stone, solid brick, clinker, and hollow concrete block.

As well as screw-in anchors, the range includes specialist push-pull prop, baseplate, pre-set, ring, and assembly rail anchors. HECO MULTI-MONTI^®-plus screw anchors are available in lengths from 25mm to 340mm, in gauges from 5mm to 20mm, and in various finishes including carbon steel, bright zinc plated, and A4 stainless steel. Numerous head options are also offered, including countersunk, pan head, hexagon, and hexagon with washer.

The anchors are certified through European Technical Assessment (ETA) and benefit from multiple technical approvals, including seismic approval, sprinkler system approval, and fire rating in concrete and brickwork.

Demonstrating their high performance and reliability, MULTI-MONTI^®-plus screw anchors have been used in numerous high profile and demanding structures. This includes the Reichstag Building in Berlin, the 4th Elbe River Tunnel in Hamburg, and the Herren Tunnel - a 780 metre long road tunnel underneath the river Trave which connects Lübeck and Travemünde.

Concluding, Stewart Taylor adds: “We are proud to be UK distributors of the HECO range because it perfectly reflects our commitment to being a trusted fastener partner. Across our entire product portfolio, we give our customers the reassurance of fixings and fasteners that are ideally suited to their intended use. This reassurance could be through relevant technical approvals, proven track records or, in the case of MULTI-MONTI^®-plus screw anchors, both.”
